Abstract

Improved pharmaceutical delivery devices which can deliver hydrophilic or polar pharmaceutically active materials, as well as optionally hydrophobic or non-polar materials, have small particles with on average a diameter below 20 microns of a drug component comprising the hydrophilic or polar pharmaceutically active material, dispersed in a silicone matrix. These devices are produced by using certain organopolysiloxane-polyoxyalkylene copolymers. Preferably an emulsion of the drug component in a silicone containing composition is made before curing the composition to an elastomer.
